Pressing F4 on java.util.Collection yields An internal error occurred during: "Restoring type hierarchy of 'Collection<E> - java.util'...". Method close()V and method close()V both claim to be at position 9 Related addresses: field 8, a FieldInt in struct NdMethod [address 460181906, size 4]: No modification report field 8, a FieldInt in struct NdMethod [address 456488394, size 4]: No modification report
Please attach full error log and provide minimal steps to reproduce. Which JDK version and vendor was used? Can it be you are using "new" JDT index?
Yes, "new" index is used.

It does not happen in a new workspace with only an empty (newly created) java project.
Please disable "new" index, it is unfortunately not maintained anymore, see bug 544898. This bug will be likely closed as "will not fix".
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
